In Mobile wallets: Having stored bitcoin or other crypto coin on your mobile wallet app, want to know if changing of device do affect the wallet? Like re_downloading the wallet app on a new device.
Bitcoin is stored in the Bitcoin Blockchain, and the Bitcoin wallet is a medium for being able to access bitcoin assets. When you have a seed or private key, then you can use it on a different bitcoin wallet, even on several devices. For this reason, highly recommended that you store the seed / private key in a safe place and not give it to anyone (who you don't trust) because this can cause your bitcoin assets to be easily stolen through other wallets from other devices.
For example, some time ago, I had tried to import private keys generated from
Electrum to
Bitcoin Core.

Maybe you want to try to access the wallet by importing its private key on the mobile wallet (noncustodial) that you use.
